Comparing Blood Pressure Cuffs in Pregnant Patients

This study is comparing two different types of blood pressure cuffs: a conical cuff for the forearm and a cylindrical cuff for the upper arm. The goal is to see how well these two cuffs agree on blood pressure readings in pregnant women. This is important because accurate blood pressure measurements are key for diagnosing conditions like gestational hypertension (high blood pressure during pregnancy) and preeclampsia (a serious pregnancy complication). You may be eligible if you are a woman aged 18 or older with a BMI of 20 or greater, and are coming to Labor and Delivery. The study will look for agreement between the cuffs' systolic (top number) and diastolic (bottom number) blood pressure readings.

Study design
This interventional study plans to enroll 110 participants. Participants will be divided into groups based on whether they have normal blood pressure or high blood pressure, and whether they are obese or not.
What's involved
After giving consent, your weight, height, and arm/forearm measurements will be taken. Blood pressure measurements will be taken while you are sitting, using both the upper arm cylindrical cuff and the forearm conical cuff.
Compensation
Not stated in the trial record.
Follow-up
Blood pressure agreement will be measured through study completion, which is an average of 1 year.
